Damn, the guy with the ponytail really wanted to scrap here, didn't he? Bill O'Brien (what a great Irish Catholic-sounding enforcer name) runs after the Rochester player, rips off his helmet, pummels the shit out of him with a series of uppercuts, and still tries to fight after he gets knocked to the ground.

It seems like O'Brien is pretty happy with his performance: his Twitter feed is full of retweeted videos of the fight.
